ULO-PCB461A is a male through-hole PCB header family with 4.2mm mating pitch in two rows. The ordering range is 2 × 2 to 2 × 10, giving 4 to 20 total contacts. Choose a vertical header or one of three right-angle mounting structures.
| Mounting code | Orientation | Retention structure | PCB contact-hole diameter |
|---|---|---|---|
| V | Vertical through-hole | Vertical body profile | Ø1.40mm |
| R1 | Right angle | Mounting ears | Ø1.60mm |
| R2 | Right angle | Locating posts | Ø1.60mm |
| R3 | Right angle | Without ears or posts | Ø1.60mm |
The component selection covers male PCB headers. Cable housings, crimp terminals and complete cable assemblies are unspecified for this model.

| Field | Code and meaning |
|---|---|
| Row and contact count | 2 × 2 to 2 × 10 |
| Connector type | M: male |
| Mounting | V: vertical; R1: right angle with ears; R2: right angle with posts; R3: right angle without ears or posts |
| Housing colour | T: transparent |
| Contact plating | 6: tin; 8: full gold flash |
N is the number of contacts per row, from 2 to 10. The mating-face pitch is 4.20mm in both directions. The PCB layout uses 4.20mm contact pitch along each row and 5.50mm between solder rows. Apply the layout tolerance of ±0.05mm and the drawing for the chosen mounting structure.
| Feature | Vertical V | Right-angle R1, R2 and R3 |
|---|---|---|
| Housing row length | N × 4.20mm + 1.3mm | N × 4.20mm + 1.3mm, excluding R1 ears |
| Contact span along row | (N − 1) × 4.20mm | (N − 1) × 4.20mm |
| Mating-face body height | 9.60mm | 10.00mm |
| Body side-length reference | 12.90mm | 12.90mm |
| Key-width reference | 3.40mm | 3.40mm |
| Lower body reference | 0.60mm | 0.40mm |
| Tail projection reference | See vertical outline | R1/R2: 3.50mm; R3: 3.70mm |
| Additional mounting holes | None shown | R1: Ø3.40mm ear mounting holes; R2: Ø3.00mm locating-post holes; R3: none shown |
R1 ears have Ø2.40mm holes in the housing, while its PCB mounting-hole reference is Ø3.40mm. R2 locating-post holes sit 7.30mm beyond the nearer solder row in the depicted layout. The right-angle contacts show a 1.14mm width reference; use each drawing's detailed dimensions and tolerances for footprint preparation.
